SURFAClNG-TOOL.

Specification of Letters Patent.

ratented April 23, 1907.

Application filed May 2, 1906. Serial Ilov 314,875.

To all whom it may concern:

Be it known that 1, Emma llonesox, a citizen of the United States, residing at Bonesteel, in the county of Gregory and State of South Dakota, have invented certain new and useful Improvements in Surfacing-'1 ools, of which the following is a specification.

This invention relates to an improved surfacing tool and is designed more particularly for the scraping and sand papering of lloors or similar surfaces.

The object of the invention is to provide a tool of this character which can be used with equal facility either as a scraper or as a sand papering machine.

A further object is to so construct the device that the angle of the scraping blade can be regulated with relation to the floor, according to the character of material being operated upon.

For a full description of the invention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to following description and accompanying drawings, in which:

Figure 1 is a perspective view showing the I device as being employed as a floor scraper;

Fig. 2 is a transverse sectional view showing the support; Fig. 3 is a sectional view through a portion of the device and shows the method of attaching the support.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The stock or body of the tool comprises two plates 1 and 2, which are preferably formed of metal and which are shown in the drawings as having an approximately rectangular shape. Each of the plates 1 and 2 is provided with a pair of parallel slots 3 which are so formed as to register when the two plates are brought together. The bit or scraping blade 4 is located between the plates 1 and 2 and is held in position by means of belts or other fastening means 5 which pass through openings in the scraping blade and are slidably mounted within the slots 3. One end of the scraping blade 4 is formed with a beveled edge 6 and the blade can be moved back and forth between the plates 2 so as to cause the beveled edge to project outwardly the desired distance. The upper plate 1 is provided with a lug or projection 7 by means of which the handle 8 is connected to the tool. Metal plates 1') lit upon opposite sides of the lower end of the handle 8 and project beyond the same so as to embrace the lug 7. A belt or pivot pin 10 is passed through the projecting portion of the plates 9 and the lug 7, and the faces of these members which come into contact with each other are preferably provided with radial corrugations 11. It will thus be seen that by loosening the bolt 10, the handle can be thrown to any desired angle and can then be securely clamped in that position. The lower plate 2 is formed at one end with a transversely disposed and downwardly projecting flange 12 which serves as a securing means for the support 13. This support 13 is preferably formed of soft or resilient material such as rubber so that there will be no danger of denting or otherwise marring the surface being operated upon, and in the present instance, the support comprises a block or red 1-1 which is surrounded by a rubber covering 15. The edges of the covering are clamped securely against the downwardly projecting llange 12 by means of a metal strip 16 which is held in position by bolts or similar fastening means.

A roller 17 is secured to the tool at the scraping end thereof and for this purpose a pair of arms 18 are provided which are secured to the top of the upper plate 1 and project beyond the end thereof. These arms 18 are preferably formed of metal strips, one end of each of which is slotted and held in po sition against the plate 1. by a bolt 19, while the opposite end is longitudinally twisted through a quarter revolution and perforated so as to form a bearing for the roller 17. Owing to the fact that the inner ends of the arms 18 are slotted, it will be apparent that they can be adjusted so as to regulate the amount the roller projects beyond the plate 1. The bolts 19, by means of which the arms 18 are held in position, are preferably located at one end of the slots 3 and are provided with heads which are counter sunk so as to lie flush with the lower face of the upper plate 1. l Vhen it is desired to employ the device as a scraper, the bit 4 is adjusted so that the beveled edge 6 thereof projects the desired amount from the plates 1 and 2 and the roller 17 is adjusted so as to throw the scraping blade 1 at the desired angle to the floor. In this connection, it will be readily understood that when the roller 17 is brought toward the plate 1, the scraping blade 4 will be thrown at a greater angle to the floor and vice versa. While using the tool in this capacity the support 13 which is formed of soft material will prevent the metal plates or the bolts therein from coming into contact with the floor in such a manner as to dent or otherwise mar the same.

Having thus described the invention, what is claimed as new is:

1. In a surfacing tool, the combination of a pair of plates, a scraping blade mounted between the plates, a roller mounted upon one of the plates and engaging with the surface to hold the scraping blade at the desired angle, and a support secured to the opposite plate and serving to prevent any injury to the surface being operated upon.

2. In a surfacing tool, the combination of a pair of plates, a scraping blade mounted between the plates, a pair of arms adjustably connected to one of the plates, a guide roller mounted between the two arms and serving to regulate the inclination of the scraping blade to the surface, and a support secured to the opposite plate and serving to prevent injury to the surface being operated upon.

3. In a surfacing tool, the combination of a pair of lates, a scraping blade mounted between t e plates, a pair of arms projecting beyond the edge of one of the plates and formed with slots, fastening members passing through the slots and serving to secure the arms to the plate, the slots permitting the arms to be moved back and forth, a guide roller j ournaled between the arms and serving to regulate the inclination of the scraping blade to the surface, and a support secured to the opposite plate.

4. In a surfacing tool, the combination of a base comprising a pair of plates, a scraping blade adjustably mounted between the plates, a pair of arms projecting laterally beyond one edge of one of the plates, the said arms being formed with longitudinal slots and being secured to the plate by fastening members passing through the slots so as to be readily moved back and forth, a guide roller journaled between the two arms and serving to regulate the inclination of the scraping blade to the surface, and a handle adjustably connected to the plate.

5. In a surfacing tool, the combination of a pair of plates, a scraping blade mounted between the plates, a guide roller mounted upon one of the plates and serving to hold the scraping blade at the desired angle to the surface, a transverse rib upon the opposite plate, and a support secured to the transverse rib and tending to prevent any injury to the surface.

6. In a surfacing tool, the combination of a base comprising two plates, a scraping blade adjustably mounted between the plates, a

pair of arms projecting laterally from one of the edges of the plate and adjustably con nected to the plate so as to be movable back and forth, a guide roller journaled between the two-arms and serving to regulate the inclination of the blade to the surface, a transverse rib located upon the opposite plate, and a support secured to the transverse rib and tending to prevent any injury to the surface. In testimony whereof I afliX my signature in presence of two witnesses.
